Heavy neutral leptons from light scalar in fixed target and forward search experiments
ShivaSankar K. A., Souvik Das, Arindam Das +1
The observation of neutrino masses strongly motivates extensions of the Standard Model, in which heavy neutral leptons acquire Majorana masses through spontaneous $U(1…
Quantum spin correlations in -mediated production at future lepton colliders
ShivaSankar K. A., Arindam Das, Sanjoy Mandal
We study quantum spin correlations in top-quark pair production at future lepton colliders in the presence of a neutral gauge boson from anomaly-free general extensions of t…
Forward Searches for Heavy Neutrinos and Bosons at FCC-hh
ShivaSankar K. A., Souvik Das, Arindam Das +1
The discovery of neutrino masses strongly motivates extensions of the Standard Model containing heavy neutral leptons and additional gauge interactions. We investigate the prospect…
Particle and Gravitational Wave Probes of Minimal Seesaw Neutrinos
Sanjoy Mandal, Rishav Roshan, Jose W. F. Valle
Observable gravitational waves (GWs) from first-order phase transitions (FOPTs) can coexist with distinct particle physics signatures. These include same-sign dilepton plus four~je…
Probing Inelastic Dark Matter via Cosmic-Ray Upscattering in NGC 1068
Eung Jin Chun, Sanjoy Mandal, Abhishek Roy
We study constraints on sub-GeV inelastic dark matter (iDM) from cosmic-ray (CR) cooling in the active galactic nucleus (AGN) NGC 1068. In dense dark matter (DM) spikes surrounding…
Probing lepton number violation at FCC-ee
Praveen Bharadwaj, Sanjoy Mandal, Rojalin Padhan +1
We propose high-multiplicity final-state signatures, such as with denoting , , as probes of lepton number violation (LN…
